In a statement from Criss Angel he said “In an effort to ensure the safety of the cast and crew, we will be moving the opening night of Supernaturalists to June 26th. This show will make you question what you see with your own eyes”.

Criss did not comment on the condition of Horsman or whether he will be able to appear in the show.
